LIQUID-LEVEL ADJUSTER FOR BOTTLE-FILLING IEACHINES.

Original application -fi1ed Gctober 15, 1923, Serial No. 668,457.

Divided and this application filed April 16, 1924. Serial No. 706,862.

To all whom it may concern.

Be it known that I, ARTHUR I. RIssnR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Liquid-Level Adjusters for Bottle-Filling Machines, of which the following is a specificat1on.

This is a division of my earlier application for bottle filling machine, Serial Number 668,457, filed October 15, 1923.

While the mechanism of this invention 15 applicable to adjusting the level of liquid in various mechanisms, it is of especial value in automatic machines for filling to a predetermined height each of a series of bottles passed through the machine and particularly to that class of such mach nes 111 which a siphon, temporarily inserted in each bottle in a supply tank, is used to convey liquid from the tank to the bottles.

The special object of the invention 1s to provide especially accurate means for main taining a constant level of l quid in the supply tank of such a -mechan1sm so that successive bottles filled by the mechanism Wlll all ultimately contain the same amount or height of liquid.

The invention consists in means attaining some or all of the foregoing and other objects; which can be easily and cheaply made; which is satisfactory in use and 18 not readily liable to get out of order.

The single figure of the draw1ngs1llustrates a side elevation largely in section of the mechanism of this invention applied actual practice to the machine of my said original application.

In the specification, the numerals of reference are for convenience of identification substantially identical with those of the original application.

The left hand two-thirds of the figure of the drawing shows the machine of the original application to which the specific mechanism of the present invention may be readily applied. In general terms, this machine includes a liquid tank 10 carried by a table 12, rota-table on a vertical axle 14', mounted on a stationary frame 16. This shaft or axle 14, and consequently the table, is rotated through the agency of gearing 1820 and shaft 22 by power mechanism not entering into this invention and not shown. This same shaft drives a longitudi," nally disposed belt 26, carried by a plurality of pulleys 28, to transport a series of hottles 36 across the front of the machine to a point where they are taken by mechanism not entering into this invention and therefore not shown, and placed upon the table 12 in the notches of a toothed wheel 42 surrounding the tank 10. Above the table and tank described are a series of siphon tubes 72 manipulatable by mechanism not entering into this invention and therefore not described, between the position shown in the left hand central portion of the figure in which they clear the bottles 36 below them, and the position on the opposite central portion of the figure in which they enter both the bottle and the tank and thus cause liquid 7 4- in the tank to flow into and fill adjacent cooperating bottles 36. The essential object of the present invention is to provide means i for maintaining the leveling of liquid 74 in tank 10 under all conditions of operation of the device, whereby exactly uniform quantities of liquid will be placed in the successive bottles 36, assuming the position shown at the right hand central portion of the figure.

This result is attained in the mechanism of this invention by making the shaft 14- a hollow pipe with its upper and entering tank 10, and its lower end connected to a hose 126 leading to a special level adjusting apparatus shown at the right of the figure.

The right hand end of pipe enters through valve 122 a tank 12 lcarried in a frame 126 carrying anti-friction rollers128 which travel vertically in guides 130 in an enclosing stationary frame. 132. The frame 126 and tank 124. is vertically adjustable in frame 132 by a screw 13% rigidly attached to frame 126 and cooperating wheel 136 bearing on the top of frame 132.

Frame 126 carries a liquid pipe 140, having a downturned end 1 12 entering tank 12 1, said pipe being continuously supplied with liquid through a pipe leading to a source not shown. On the lower end of pipe portion 142 is a conventional valve 1414i and float 146, shown closed in the figure which shuts off liquid from pipe 140 from entering tank 124: whenever the liquid 7 at in tank 12 causes float 14:6 to reach the shown position on pipe; end: 142? and causes liquiehto flow" from saidpipe end'lnto the tan'lt'when'ever the llquld 111 the tank is so positioned-that-- interconnnunication throng-hi pipe 120;? it

is obvious that the operator can by operating wheel 136*to bodily raise or lower tank 1% and its level control float ineoh'anis'in change the level of liquid in tank. 10 Without raising its1'co'V'en 150 and avitlio ut'getting in'the way 'of any of its siph'on's. By the useof thisapparat11s;tl1e level-of liquid 74: in tank 10 can be adjusted to'sinall fractions of an i11ol1,' an importantrequirement in hot tle filling.

Having thus. described my invention,

what I claim as new and desire to secure by Letters Patent is:

1. 111 a 'bottlezfilling machine;- a vertically immovable tank from which liquid is adapted-to be siphoned into bottles an elevatable and depressibletank-from which liquid is supplied-tosaidfirst mentioned tank,"

and means to maintain liquidat a constant level air/said second-tank;

2. In a bottle filling machine, a tank from which liquid is adapted to be siphoned into bottlesyand means for supplying liquid to said tank including a second tank that is vertically adjustable and that is equipped with a fioat c'ontrolled Valve for maintaining a constant l'eve'lof liquid' the-rein.

in witness whereof; I have hereunto sub scrlbe'd my nain'ezi mman. arssnre:
